NYC's most infamous crimes: Serial killers, scandals and shootings

William Magear "Boss" Tweed is shown in this undated photograph. The legendary political boss, who led New York City's Tammany Hall Democratic machine from 1863 until 1872, was convicted of corruption and was accused, by some estimates, of stealing up to $1 billion to $4 billion from taxpayers in today's dollars. Tweed died in prison in 1878. (Credit: AP)
